A long DNA segment in a linear nanoscale Paul trap.
We study the dynamics of a linearly distributed line charge such as single stranded DNA (ssDNA) in a nanoscale, linear 2D Paul trap in vacuum. Using molecular dynamics simulations we show that a line charge can be trapped effectively in the trap for a well defined range of stability parameters. We investigated (i) a flexible bonded string of charged beads and (ii) a ssDNA polymer of variable le...

متن کاملCryogenic linear Paul trap for cold highly charged ion experiments.
Storage and cooling of highly charged ions require ultra-high vacuum levels obtainable by means of cryogenic methods. We have developed a linear Paul trap operating at 4 K capable of very long ion storage times of about 30 h. A conservative upper bound of the H(2) partial pressure of about 10(-15) mbar (at 4 K) is obtained from this. External ion injection is possible and optimized optical acce...
متن کاملQuantum nondemolition measurements in a Paul trap
In this work a family of quantum nondemolition variables for the case of a particle caught in a Paul trap is obtained. Afterwards, in the context of the so called restricted path integral formalism, a continuous measuring process for this family of parameters is considered, and then the corresponding propagators are calculated. In other words, the time evolution of a particle in a Paul trap, wh...
متن کاملTransient Antihydrogen Production in a Paul Trap
Although positrons and antiprotons have vastly different masses, we show that it is possible to store both particle species simultaneously in a Paul trap, using the space charge of the positron cloud as a trap for the antiprotons. Computer simulations confirm the validity of this new trapping mechanism. In addition, the simulations show transient antihydrogen production that manifests itself in...
